Metabolic effects of rexinoids: tissue-specific regulation of lipoprotein lipase activity.

abstract：:The anti-arrhythmic quinidine has been reported to be a competitive inhibitor of the catalytic activities of human liver P-450DB, including sparteine delta 2-oxidation and bufuralol 1'-hydroxylation, and we confirmed the observation that submicromolar concentrations are strongly inhibitory. Human liver microsomes oxid...
